TIN-STICKER MACHINE.

Application filed January 25, 1921.

To all 20 item it may concern:

Be it known that I, JAMES CARArILInIs, a citizen of the United States, residing at Sabraton, in the State of Vest Virginia, have invented new and useful Improvements in Tin-Sticker Machines, of which the following is a specification.

This invention relates to machines for separating sheets of metal and similar material, and more particularly to what I have termed a. sticking machine.

One of the main objects of the invention is to provide a machine of the character stated of simple construct-ion and operation which may be readily worked by a single operator. A further object is to provide a machine having'means for gripping sheets of metal and for .tearing the same apart. Further objects will appear from the detailed description;

the drawings:

Figure 1 is a front view of a machine constructed in accordancewith my invention.

Figure 2 is a section taken substantially on line 2-2 of Figure 1.

Figure 3 is a detail of the grippers. Figure 4 1s a central vertical section through the machine taken from front to back.

Figure 5 is an end view of the machine.

Figure 6 is a fragmentary detail showing the latch for holding the lever depressed.

It is the present practice in rolling mills to roll iron and similar metals in sheets which come from between the rolls in stacks or masses, these sheets after they leave the rolls being torn apart or separated by hand, this operation being termed sticking. The primary object of this invention is tao provide a machine of simple construction by means of which. this sticking operation may be performed more quickly and easily than by hand. Vithtlnsobject in view provide a boXlike casing 1 which is supported by a suitable frame 2 mounted on casters 3 so as to be readily, moved toward or away from the mass or stack of sheets. 'Two gripping members t'of plierlike construction are slidably mounted in casing 1, the heads 5 of these members projecting through a slot 6 extending longitudinally of the back wall. 7 of the casing. Each arm of pliers 4. is provided with a supporting: caster 8 to facilitate Specification of Letters Patent.

movement of the gripping members toward and away from each other. The forward end portions of the arms of the gripping members slide on a guide strip 9 secured in the front of easing 1, and outward movement of these members is prevented by a stop strip 10 which projects above strip 9. The members at are normally held in open position by expansion springs 11. Each arm of member 4 is provided at its forward end with an upwardly projecting peg or pin 12, these pins being positioned directly below a bell-shaped member 13 slidably mounted on a bar 14 extending longitudinally of easing 1 at the front thereof. This bar is connected at one end by a link 15 to a bracket'lb' secured to the end of the casing. An expansion spring 17 confined between link 15 andt-he adjacent end of casing 1 co-operates with an expanslot in the other end of the casing and confined between the same and bar 14 to hold the bar raised. A

- lever 19 is pivoted at 20 in a bracket 21 secured to end 1 of easing 1, and extends across bar let which projects through the end wall of the casing. This lever extends through a slot 21 in a bracket 22 secured to end 1 of the casing at the back thereof, this slot being inclined downwardly and inwardly toward the casing; Lever 19 fits into a notch 23 in bar 1 1 so that when the lever is depressed it causes downward and inward movement'of bar 14 due to the inclination of slot 21. This serves to force the members 13 over pins 12 forcing the pins toward one another and thus closing thehcads 5 of 1nembers 4 so as to cause them to grip a sheet inserted between the aws 5. A gravity latch outer wedge members which are well adapted to be forced between sheets of a stack which is stood on edge. After this has been is connected by a done, the gripping members are closed in the manner described so as to grip the sheets between jaws 5 after which the members 4 are forced away from each other toward the ends of the casing thus tearing the sheets apart.

For the purpose of forcing members 4 away from each other I provide a toggle structure 27 consisting of pairs of links 28 and 29 which are pivotally connected at their outer ends at 30. The lower end portions of links 29 intersect and are pivoted at 31 to studs 32 secured to the inner arms 4 of members 4. The lower ends otlinlr. 28 project beyond links 29 and are shaped to provide forks 33 which carry rollers 34 which travel between guide strips 35 secured to the inner faces of the end walls of easing 1. The links 28 are pivoted at their upper ends, at 36 to the lower end of a plunger 3'? slidable through top 1 of easing 1. This plunger is provided at its upper end with fork 38 between which and the top of the casing is con lined an expansion spring 39'mounted about the plunger. A lever 40 is pivotedat its inner end to a standard 41 secured to the top wall of the casing, and is connected by pin and slot connections 42 to fork 38. At its outer end lever 40 is pivoted, at 43, to a fork 44 carriedby a pull rod 45 to the lower end of which is loosely connected a treadle 46;

In using the machine, the stack of sheets is placed on edge after. which the machine is moved into position adjacent to the front of the stack and is then forced toward the stack so as to force the jaws 5 of the gripping members between the sheets. The gripping members are then closed so as to tightly grip the sheets between the jaws, after which plunger 37 is depressed by pressing on treadle 46 thus forcing the gripping members 4 away from each other and tearing the sheets apart. During this operation, the

members 13- travel freely on bar 14to a greater or lessextent. The jaws' 5 of the gripping members 4 may be closed or'opened to the desired extent-for gripping the de sired number oil sheets. After the sheets have been separated, by releasing treadle 46 from pressure and releasing lever 19, the gripping members and associated parts and the members 1.3, are permitted to return to normal position, this being eilected by the springs 24 and Hand 18 and spring 39.

The jaws 5 of the gripping members are n'eferably, though not necessarily, provided with face plates 47 of hard steel which are removably secured by screws 48, or in any other suitable manner thus permitting re-.

newal of these jaws when desired. This is a desirable feature of the invention since the gripping faces and points of the jaws are subjected to great wear and strain in use. As Wlll be understood, slight changes in construction and arrangement of parts of the invention may be resorted to without departing from the field and scope of the same, and I intend to include all such variations, as fall within the scope of the a pended claims, in this application in which a preferred form only of my invention is disclosed.

lVhat I claim is:

1. In a machine oi the character stated, a casing, gripping members slid-able longitudinally of the casing, means for normally holding said members adjacent to each other, means for normally holding the gripping members open, means for closing the gripping members and permitting movementof the same longitudinally of the casing, and means for moving the gripping members in opposite directions.

2. in a machine of the character described, a casing, gripping members slidably mounted in the casing for movement toward and away from each other, t

necasing being provided through its back wall with an elon gated slot and the. heads of said members projecting through said slot, means for preventing movement of the gripping members toward the front of the casing, means for normally holding the. gripping members adjacent to each other, means for normally l'lOlClllig the gripping members open, means for closing the gripping members and permitting movement of the same away from each other, and means for forcing said gripping members in opposite directions.

3. in a machine of the character described, a casing provided through its back wall with an elongated slot, gripping members of plierlilre construction slidable in the casing for movement toward and away from each other and having their heads projecting through said slot, means for normally holding said members open, meansior holding the gripping members in positions adjacent to each other, means for closing the gripping members while permitting movement of the same away from eachother, and means for forcing the gripping members away from each other.

4. In a 1n achine of the character described,
